According to the papers, Saide claims that LaBeouf readily loaned him $800,000 in 2009 -- as a result of economic downturn -- and allegedly said that "we were family and that he had more money than [he] could ever need." The filing also notes that LaBeouf reportedly made $20 million for his last two Transformers films and $8 million for Wall Street: Money Never Sleeps.

LaBeouf is seeking judgment for the $800,000 loan plus $39,999.95 in interest. The actor claims that his uncle signed a loan agreement agreeing to pay the money back in 15 installments with interest beginning in January of 2011. "Defendant has failed to pay a single installment of either principal or interest to me or to any entity controlled by me," LaBeouf says in an affidavit.

Saide's affidavit says that he considers the matter to be "a private family dispute" that "should not have been elevated" to court action. He is seeking to fight the money judgment, writing that the loan agreement in question says that the debt could be satisfied by giving LaBeouf and his mother a 25 percent share of his companies. In the doc, Saide says that he has been the owner of a New York staffing agency for more than 30 years.

The Hollywood Reporter has reached out LaBeouf's publicist for comment and will update with a response. LaBeouf's lawyer declined to comment.
